Implementation Partner in Switzerland for Business Center/NAV

We are a rather large NGO in Switzerland and so far our traditional method of selecting an implementation partner for Navision has been a complete failure. In the proposal/pitch phase we were always convinced to have found a competent partner, but in the implementation phase we were disappointed: there was a lack of expertise, knowledge and commitment.
Is there anyone in Switzerland who has implemented Business Center/Nav with a partner and is satisfied? Please tell us.
Thank you very much!


I do not know Partners in Switzerland but know people in UK, Denmark, UAE.
